The investigators are comparing the combination of a stainless steel repair and aggressive early active range of motion rehabilitation protocol for flexor tendon lacerations in the hand with a current, accepted treatment offered at our institution. Outcomes to be assessed will be time to return to work, joint range of motion in the injured fingers, and any potential complications that may arise (ex: surgical infections or repair rupture). All proposed treatments included in this study are currently being offered at our institution, but not in a randomized fashion.
This study will serve as a pilot-study for a future randomized controlled trial. Adult patients with zone 2 flexor tendon lacerations of the hand (anatomically from the A1 pulley of the hand to the insertion of the flexor digitorum superficialis) who have presented to the emergency room acutely (within 1 week of injury) at the Health Sciences Center in Winnipeg will be asked for their participation in this study. Consent will be obtained by a plastic surgery resident either in the emergency room or in the plastic surgency emergency decanting clinic. The investigators will include twenty-four patients in the study, randomized into one of two treatment groups (groups A and B) by block randomization. Randomization will be done once patients agree to participate in the study. All patients will be booked for surgery on the emergency slate. Each treatment group will be treated by a single surgeon who is an expert at treatment of these injuries. Group A patients will have their laceration(s) repaired using a modified Becker repair technique using stainless steel suture in the operating room, and then will proceed to undergo an aggressive early active range of motion rehabilitation administered by the hand therapists at HSC. Group B patients will undergo a double-locking loop suture repair using polypropylene. They will then undergo a less aggressive active range of motion rehabilitation protocol which is currently offered to patients at our center. Follow-up will occur in plastic surgery outpatient clinic at post-operative weeks 1, 2, 4, 6 and 12. Follow-up with hand therapy will be at the discretion of the therapists. At each visit with hand therapy, joint range of motion will be assessed at the PIP and DIP joints in the affected fingers. Final range of motion will be assessed using the Strickland system for evaluating flexor tendon surgery outcomes, and will be done by a blinded hand therapist.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Stainless steel MGH | Experimental | Patients in this study arm will have their flexor tendon laceration repaired using stainless steel suture (size 3-0) in an MGH repair technique. They will then undergo aggressive early active range of motion rehabilitation post-operatively. |
|
| Polypropylene DOLL | Active Comparator | Patients in this study arm will have their flexor tendon laceration repaired using polypropylene suture (size 3-0) in a double-locking loop repair technique. They will then undergo aggressive early active range of motion rehabilitation post-operatively. |

| Aggressive early active range of motion rehabilitation | Behavioral | Patients undergoing this form of rehabilitation will have their splints discontinued at 4 weeks and ideally will be back at work at normal duties by 6 weeks. This rehabilitation uses more movement at a faster progression than other early active range of motion protocols. |
|
| Early active range of motion rehabilitation | Behavioral | Patients undergoing this form of rehabilitation will have their splints discontinued at 6 weeks and ideally will be back at work at normal duties by 10-12 weeks. This rehabilitation uses less movement at a slower progression than the early AROM rehabilitation protocol specified in the experimental group |

At each follow-up visit with the clinician or occupational therapist, the presence of a rupture will be assessed for clinically. Alternatively this will be recorded if the patient presents to the emergency room with a flexor tendon rupture
| Post-operative weeks 1, 2, 4, 6 and 12 |
| Infection | At each clinic visit, the patient will be assessed clinically for the presence or absence of an infection. This will also be noted if the patient presents to the emergency room. | Post-operative weeks 1, 2, 4, 6 and 12 |
| Attendance with follow-up clinic and occupational therapy | The patient's attendance will be determined at each clinic or occupational therapy visit. | Post-operative weeks 1, 2, 4, 6 and 12 |
| Use of oral analgesics | At each clinic visit, the patient will be asked if they are still using oral analgesics | Post-operative weeks 1, 2, 4, 6 and 12 |
| Oral antibiotic usage | At each clinic visit, the patient will be asked if they are using oral antibiotics. | Post-operative weeks 1, 2, 4, 6 and 12 |
| Wound dehiscence (breakdown) | At each clinic and occupational therapy visit, the patient will be assessed to determine if a wound dehiscence (breakdown) has occurred. | Post-operative weeks 1, 2, 4, 6 and 12 |
| Use of occupational therapy adjunctive treatments | At each occupational therapy visit, it will be recorded that they are either using or not using occupational therapy adjunctive treatments (ex: coban tape, ultrasound or electrical stimulation) | Post-operative weeks 1, 2, 4, 6 and 12 |
